Improvement in whip-forming molds



UNITED STATES PATENT OEETCE JOHN J. BOHLER, OF WESTFIELD, MASSACHUSETTS.

IMPROVEMENT IN WHIP-FORMING MOLDS.

Specification forming part of Letters Patent No. 153,011, dated July 14,1874; application tiled April 18, 1874.

To all lwhom t may concern:

Be it known that I, JOHN J. BOHLER, of Westfield, in the county ofHampden and State of Massachusetts, have invented a new and valuableImprovement in Whip-Molds; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationofthe same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawing is a representation ot' a front view of mywhip-mold, and Fig. 2 is a sectional View of the same. Figs. 3 and 4 aredetail views.

This invention has relation to means for molding whips which arecomposed of `cores surrounded by narrow strips of leather; and consistsin the novel construction and arrangement of the molds, as will behereinafter more fully explained.

The press which I prefer to employ is constructed as follows, referencebeing had to the annexed drawings: A and B designate two strong bars,which are firmly secured together, at a suitable distance apart, bymeans of four perpendicular rods, a a. D designates a follower, the endsof which are guided between the said rods a. This follower is moved upand down by means of a screw, C, which is tapped through the headbar B,and provided with a hand-wheel, C', by which the screw is turned. Gdesignates a whip-mold, which is composed of two longitudinal sections,g g, of suitable length, and ofsuch width as to re ceive twomold-spaces, and allowing two whips to be molded at one and the sametime. The

section g has two tapering grooves, c e, in it, the largest ends ofwhich are at opposite ends of the section, for the purpose of allowingthe grooves to be brought very near together, they being separated by avery narrow diagonal partition. The section g is constructed with twotapering tenons, i f1?, having transversely concave surfaces, whichtenons are adapted to fit into the grooves c e of the section g, asshown in Figs. 2 and 4, and thereby form the chambers in which the whipsare molded.

It will be seen that the molds can, by my arrangement of the grooves andtenons, be made very compact; also, that they can be removed from thepress and applied to it at pleasure; also, that any desired number ofthe molds can be piled up in the press, and acted on by the follower l).

I am aware that whip-molds have been per manently constructed with theirpresses, which requires a pressy for each mold, and therefore I make nobroad claim to such feature.

What I claim as new, and desire to secure by Letters Patent, is-

The detachable molds G, constructed with the grooves e e and taperingtenons t' t', forming the 1nold-chambers, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
